BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dianthus, botanically known as caryophyllus L., and hereinafter referred to by the variety name ‘KLEDP20346’. ‘KLEDP20346’ originated as a naturally-occurring, whole plant mutation from the Dianthus parent ‘KLEDP07089’ (unpatented) in May 2016 in a greenhouse in Stuttgart, Germany.

In August 2016, ‘KLEDP20346’ was first vegetatively propagated by vegetative stem cuttings in Stuttgart, Germany. ‘KLEDP20346’ was found to reproduce true to type in successive generations of asexual propagation in Latina, Italy and Stuttgart, Germany via vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of ‘KLEDP20346’ when grown under normal horticultural practices in Stuttgart, Germany.

-   -   1. Double red-purple flowers having red-purple macules; and     -   2. An upright and compact plant habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Dianthus plant is illustrated by the accompanying photograph of a 13-week-old plant taken in May 2019 and grown in a greenhouse in Stuttgart, Germany. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is a whole plant photo of ‘KLEDP20346’ and shows the foliage, buds, and flowers.

DESCRIPTION

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDP20346’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected in March 2022 from plants that were potted in week 41 in 2021 and grown in a greenhouse. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^(th) edition (2007).
